Which protocol does ACAS utilize for gathering data from endpoints?

ACAS utilizes the Simple Network Management Protocol (SNMP) for gathering data from endpoints due to its effectiveness in network management and monitoring. SNMP is designed specifically for managing devices on IP networks, making it an ideal choice for system administrators to collect information on the status and performance of various elements within a network infrastructure.

Using SNMP enables ACAS to query devices for performance metrics, configurations, and other essential data needed for compliance assessments. The protocol works by sending requests to agents on devices, which then respond with the requested data. This ability to efficiently gather data across a wide array of devices, such as routers, switches, and servers, allows ACAS to maintain comprehensive oversight of IT environments and ensure they meet compliance standards.

In contrast, the other protocols listed do not serve the same purpose for gathering endpoint data. Hypertext Transfer Protocol (HTTP) is primarily used for transferring web content and does not focus on device management. Remote Desktop Protocol (RDP) is specifically for remote desktop access, not data collection on endpoints. File Transfer Protocol (FTP) is designed for transferring files rather than monitoring or managing device performance. Thus, SNMP stands out as the most suitable and efficient protocol for ACAS's operational needs.
